I’d certainly agree with your identification of the main perk. I’m retired now but taught for 30 years, mainly 16-19 sector. I really miss the students, they are funny, vulnerable, challenging and usually a joy. It’s a great feeling when you hear of or meet a student who has gone in to do something amazing with their life, the best buzz ever to have been even a bit involved in creating who they are now. But the admin is crippling. I’ve always thought the job itself is a bit like being in a 6 hour play, with very brief intervals, where you have to engage, entertain and hopefully educate 30 people all at the same time - truly performance art!
